Contribution to the green economy:

According to Huppert & So (2011, 'Flourishing Across Europe: Application of a New Conceptual Framework for Defining Well-Being.'), optimism is one of the components of flourishing. It can also be seen to be a proxy for a successful society, as people anticipate life to be getting better. Therefore a positive trend could indicate success in the transition towards a Green Economy.

Potential misinterpretation:

Might there be a lack of extensive optimism about the future, while the present is regarded positively?
